Electric window courtesy issue 965

[mivvi]

Hi All, I have searched this site for info on this problem but to no avail.

Anyhow, working on a car for a friend and I believe its a 965? I could be wrong there but its wide body turbo if that's any help. Supposed to be quite a rare bit of kit.

The problem is that when you switch the ignition off, its supposed to close the windows automatically. The passenger one works ok but not the drivers side? Both windows work fine off their switches but not this function? Anyone got a diagram of the circuit?

Thanks!
